Consumable replacement guidelines

To facilitate consumable replacement, keep the following guidelines in mind when setting up the printer:

  • Sufficient space is required in the front and rear of the printer for removing consumable items

  • The printer should be located on a flat, sturdy surface

  • 102 mm (4 in) of space is required on the sides of the printer to ensure proper ventilation

CAUTION: HP recommends the use of HP products in this printer. Use of non-HP products may cause problems requiring service that is not covered by the Hewlett-Packard warranty or service agreements.

The following table lists the replacement intervals for printer consumable items and the control panel messages prompts for replacing each item.

NOTE: To view the percent life remaining on the fuser, transfer and drum kit, press the Menu key on the control panel until INFORMATION MENU displays. Then press the Item key until the percent life for those kits display.

* Approximate average A4/letter-size page count based on 5% coverage of individual toner colors. Page counts are estimations, and usage conditions and print patterns may cause results to vary.

** Approximate life is based on 2,000 pages per month.

*** The 6,250 color pages or 25,000 black-only pages; based on two-page, A4/letter-sized print jobs. Actual number of pages will vary depending on individual customer usage. Factors affecting page yield include color versus black-only printing mix, paper size, typical job length and complexity, and automatic duplexing.

NOTE: When the printer's control panel shows a drum kit low message, 20% of the drum life remains. When the control panel gives a fuser kit low or transfer kit low message, at least 5% of the life remains.

Cleaning the printer

Clean excess toner from the printer

Toner from the yellow, magenta, and cyan print cartridges will accumulate on the flaps that cover the print cartridges. Although this accumulation of toner does not cause print defects, the excess toner needs to be cleaned from the flap occasionally. Clean the flap covering the print cartridge and other excess toner from the printer when replacing print cartridges. There is a toner cloth provided with each replacement print cartridge to clean the toner from the printer. For more information about cleaning the printer, refer to the instructions included with the replacement print cartridge.

CAUTION: Do not use the toner cleaning cloth on the drum, developer sleeves in the print cartridge, or transfer rollers. This can damage these units and cause other print quality problems.

If toner has built up on the print cartridge, it may fall on the transfer roller, which causes streaking on the printed media. To clean the toner from the transfer roller, print several blank pages until the streaking stops.

Clean the toner density sensor

The toner density sensor should be cleaned whenever the imaging drum is replaced or the control panel message DENSITY SENSOR OUT OF RANGE displays.

CAUTION: To avoid scratching the sensor, do not clean it with any paper products.

To clean the toner density sensor

  1. Open the lower front drawer, remove the cleaning brush mounted inside, and then close the drawer.

    Figure 4: Removing the cleaning brush

  2. Pull open the top front drawer.

    Figure 5: Pulling open the top front drawer

  3. Remove the imaging drum by the blue handle.

    Figure 6: Removing the imaging drum

  4. Use the cleaning brush to remove all dust and toner particles from the sensor, as illustrated.

    Figure 7: Removing particles from the sensor

  5. Re-insert the imaging drum.
